The Sonic Devestator. $300.00 assembled. Scary sausages.
This handheld space age weapon of the future is powered by (2) 9 volt batteries conatined [sic] within the handle. It is capable of emitting intense ultrasonic blasts from its output transducer…It is effective for approximately 20ft but some people are even effected at distances as great as 50ft… A good example of the type of irritation it produces is to say its like somebody scratching their fingernails on a chalkboard but at 130 decibels which is about the same sound output levels experienced at a rock concert.
